执行语句：

POST:

http://127.0.0.1:9200/demo/_search

body:

{    
    "query": {
        "bool": {
            "filter": [
                {
                    "match": {
                        "userid": "f8d3e9ad7ec3482a9f92318eb18f8173"
                    }
                }
            ]
            
        }
    },
    "from": 0,
    "size": 200000000
}

原因：从上面的报错信息，可以看到ES提示我结果窗口太大了，目前最大值为10000，而我却要求给我10000000。并且在后面也提到了要求我修改index.max_result_window参数来增大结果窗口大小。

解决：

body：

{
    "index": {
        "max_result_window": 100000000
    }
